Install driver of TDM card with Free PBX

Hi
I am Leonel
I want to connect PABX Matra Nortel (with analog phones) with mY Asterisk Server via FXS on PABX and FXO on my TDM Card on Asterisk.
But I don’t have the login and password to do this in command Line (on terminal).
I just have a login and password of GUI free PBX.
Is-it possible to do all steps in GUI Free PBX.
Especially loading the card driver is done with the command modprobe wctdm ?
Is it possible to loading the driver card on GUI Free PBX ?
If not, what can I do ?

Is it possible to crack or change the login and password of Command line.

Thanks
